COLUMN non s'rnam-nornnns.

To all whom it may concern:

Be it known that we, HARTSELL H. Cnoss and \Vamnn F. \Vnaronronn, citizens ofthe United States, residing at Hendricks, in the county of Tucker and State of Vest Virginia, have invented new and iisefnl Improvements in Columns for Steam-Boilers, of which the following is a specification.

This invention relates to water columns for boilers and the objectof the invention is the provision of a column having means whereby the height of the water in the boiler may be readily seen Without operating the pet cocks and whereby the main stems of the pet cocks may be removed and properly ground without drawing the steam and whereby, when the main valve stem is closed,"the height of the water in the boiler maybedetermined independent of the pet cock.

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawing, which forms a partof this application, and in which Figure 1 is a side elevation. Fig. 2 is a section taken through the column on the line 22 of Fig. 1. Fig. 8 is a section through one of the pet cocks.

Referring more particularly to the drawing, 1 represents a boiler and Qindicates by dotted lines the-normal water level. EX- tending from the boiler below and above the normal water level are pipes 3 and 4;, the former of which is connected to the lower part of a water column 5 and the latter pipe 4 connected to the upper part. This column is preferably cast as an integral part although it may beconstructed in any other suitable manner and is hollow to receive the water .and steam from the boiler.

Secured in each side directly opposite each other are sight glasses 6. The sight glasses 6 are arranged in suitable alinedopenings at the opposite sides of the column 5 and threadcdly secured within said opening and surrounding the sight glasses are annular members 1 1 having flanges 15 which bear against. the outer surface of the column, and internat flanges 15 bearing against the outer surface of the sight glasses. Each of said annular members has a reduced threaded portion 17 upon which is threadedly secured a flanged ring member 16, the flanged portion 16 of which bears against the op- Specification of letters Patent.

posite surface of the sight glasses 6 to retain the same positioned within the openings of the column 5. Extending at right angles to the line of sight therethrough is a plurality of pet cocks 7. These pet cocks 7 each comprises a casing 8 having a passage 9 extending therethrough to the discharge nozzle or spout 10. The passage is closed by a main needle valve 11 and an auxiliary valve 12 is also arranged in the casing and is adapted to close the passage when the main needle valve is removed for grinding. The entire column may be cut off from the boiler by means of valves 13 and 14 located in the pipes 3 and 4 respectively.

It is a well-known fact among engineers that the pet cocks formerly used have to be ground at frequent intervals to secure proper seating. ln order to do this the steam has to be drawn from the boiler which entails a considerable amount of labor and also considerable lossof time. By using the type of pet cock illustrated, in combination with the sight glasses,the main valves may be properly ground and at the same time the condition of the water in the boiler readily ascertained by an inspection of the column through the sight glasses, the latter being alined to permit better inspection.

Having thus described the invention, what we claim as new is A water gage comprising a tubular body having a series of alined spaced openings at the opposite sides thereof, annular members threaded in said openings and having flanges bearing against said tubular body and having internal flanges adjacent the first mentioned flanges, said members having a reduced portion to provide an annular shoulder, transparent members secured Within said annular members, each having.

a reduced portion on one face thereof to provide a shoulder adapted to bear against said internal flanges, and a flanged ring threadedly secured to said. reduced portion of the annular member and having 1ts flanged portion bearing against the opposite face of the transparent member.

In testimony whereof we aflix our signatures in presence of two Witnesses. HARTSELL H. CROSS. WALTER 13. WRATGHFORD. Witnesses:
